You can create a radar plot chart using code or the designer. The following image shows a Radar point type chart.

Point Chart, example of Radar plot

For details on the API, see RadarPlotArea class.

The following classes are also available when creating Radar plot type charts:

Using Code

  1. Use the RadarPointSeries class to add data to a Chart control.
  2. Use the RadarPlotArea class to create the plot area.
  3. Set the location and size of the plot area.
  4. Add the series to the plot area.
  5. Create a label and legend for the chart.
  6. Create a chart model and add the plot area, label, and legend to the model.
  7. Create a chart and add the chart model to it.

Example

The following example demonstrates using unbound data to create a Radar chart.

C#
Copy Code 
RadarPointSeries series0 = new RadarPointSeries();
series0.SeriesName = "Series 0";
series0.Values.Add(1.0);
series0.Values.Add(2.0);
series0.Values.Add(3.0);
series0.Values.Add(4.0);
series0.Values.Add(5.0);
RadarPointSeries series1 = new RadarPointSeries();
series1.SeriesName = "Series 1";
series1.Values.Add(2.0);
series1.Values.Add(3.0);
series1.Values.Add(4.0);
series1.Values.Add(5.0);
series1.Values.Add(6.0);
RadarPlotArea plotArea = new RadarPlotArea();
plotArea.Location = new PointF(0.2f, 0.2f);
plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series0);
plotArea.Series.Add(series1);
LabelArea label = new LabelArea();
label.Text = "Radar Point Chart";
label.Location = new PointF(0.5f, 0.02f);
label.AlignmentX = 0.5f;
label.AlignmentY = 0.0f;
LegendArea legend = new LegendArea();
legend.Location = new PointF(0.98f, 0.5f);
legend.AlignmentX = 1.0f;
legend.AlignmentY = 0.5f;
ChartModel model = new ChartModel();
model.LabelAreas.Add(label);
model.LegendAreas.Add(legend);
model.PlotAreas.Add(plotArea);
chart2DControl1.Model = model;
VB
Copy Code 
Dim series0 As New FarPoint.Win.Chart.RadarPointSeries()
series0.SeriesName = "Series 0"
series0.Values.Add(1.0)
series0.Values.Add(2.0)
series0.Values.Add(3.0)
series0.Values.Add(4.0)
series0.Values.Add(5.0)
Dim series1 As New FarPoint.Win.Chart.RadarPointSeries()
series1.SeriesName = "Series 1"
series1.Values.Add(2.0)
series1.Values.Add(3.0)
series1.Values.Add(4.0)
series1.Values.Add(5.0)
series1.Values.Add(6.0)
Dim plotArea As New FarPoint.Win.Chart.RadarPlotArea()
plotArea.Location = New PointF(0.2F, 0.2F)
plotArea.Size = New SizeF(0.6F, 0.6F)
plotArea.Series.Add(series0)
plotArea.Series.Add(series1)
Dim label As New LabelArea()
label.Text = "Radar Point Chart"
label.Location = New PointF(0.5F, 0.02F)
label.AlignmentX = 0.5F
label.AlignmentY = 0F
Dim legend As New LegendArea()
legend.Location = New PointF(0.98F, 0.5F)
legend.AlignmentX = 1F
legend.AlignmentY = 0.5F
Dim model As New ChartModel()
model.LabelAreas.Add(label)
model.LegendAreas.Add(legend)
model.PlotAreas.Add(plotArea)
chart2DControl1.Model = model

Using the Chart Designer

  1. Select the PlotArea Collection editor.
  2. Click the drop-down button on the right side of the Add button (lower, left side of dialog).
  3. Select the RadarPlotArea option and set properties as needed.
